Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

In Cameroon, rangelands occupy about 20 % of surface area; provide critical habitat to many animal and
plant species; offer many vital goods and services to society and are home to pastoralists, agropastoralists,
crop farmers, fishermen and hunter-gatherers, who for centuries co-existed peacefully. In
recent years this harmony is being threatened by changing land use patterns, poor land use planning and
poor recognition of ownership rights. Despite efforts by state and non-state actors to improve pastoral

Following the example of Tiffen et al. on Machakos, Kenya, new macro-based evidence was collected in Machakos, the neighbouring Kitui district and in Benin, Cameroon and the Philippines, to assess the factors à la Boserup, inducing transitions towards sustainable land management, such as terracing, stone bands etc. We find that relative scarcity of land can be seen to induce technical changes, in the sense of Hayami & Ruttan, that correspond to the new
relative scarcity, making higher man-land ratios the optimal choice.
